Application filed January 10, 1919. Serial No. 270,519.

To all whom it may concern: I

Be it known that I, ALFRED JOHNSON, a

citizen of the United States, residing at.

Grafton, in the county of Walsh and State of North Dakota, haveinvented certain new and useful Improvements in Locomotive Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will on able others skilled in the art to which it appertains to make and use the same.

This invention relates to locomotive attachments, and the. primary object of the invention is to provide an improved means forconducting the, smoke and cinders from the smoke stack of the engine to a point below the locomotive body, so as to eliminate cinders from falling upon the railroad coaches and upon objects along side of the railroad track, so as to prevent the possibility of the same being put on fire by the live cinders.

Another object of the invention is to provide means for extending a cinder and smoke conductor through the tender of the locomotive, so as to preheat the feed water for the locomotive prior to its entrance into the boiler.

A further object of the invention is to provide animproved means for arranging the smoke and cinder pipes in the tender, so as to increase the radiating surface thereof and provide-means for allowing the condensation of water in the smoke and cinder pipes to fall into the tender.

to provide an electrically operated. fan in the smoke and cinder conducting pipes so as to effectively increase the draft of the locomotive.

A still further object of the invention is to provide an improved device of the above character, which is durable and efficient in use, one that is simple and easy to manufacture, and-onethat can be applied to the ordinary type of locomotive Without materially changing the construction thereof.

With these'and other objects in view the invention 7 consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part thereof, 1 in which i Figure 1 is a side elevation of the locomotive and tenderv showing. the improved smokeand cinder conductor attached thereto,

Fig. 2 is a plan view of the same,

Fig. 3 is a front elevation of the locomotive showing the arrangement of the smoke conductor pipes,

Fig. 1 is a detail cross section taken through the smoke conductor, and

Fig. 5 is a detail cross section through the locomotive tender.

Fig. 6 is a section taken on the line 66 of Fig. 4. v

Referring to the drawings in detail,

,wherein similar reference characters designate corresponding parts, throughout the several views, the numeral-1 indicates the improved smoke conductor which is adapted to be secured to the smoke stack 2 of an ordinary locomotive The locomotive 3 includes the boiler 1 and cab 5. A tender 6 is secured to the locomotive 3 in the ordinary manner. i

The smoke conductor 1 includes a downwardly and rearwardly inclined pipe 7,

preferably circular in'cross section which has the upper end thereof secured to the.

cinders from the smoke stack into the pipe 7.

The lower end of the pipe 7 is contracted as at 9 and terminates 111 a pair of relatively small conductor pipes 10 and 11 which converge outwardly and rearwardly from the pipe 7. The pipes 10 and 11 are curved downwardly as at 12 over each side of the boiler A and are thenbent rearwardly as at 14:. The pipes 10 and 11 extend on each side of the boiler and project beyond the cab 5, and are connected to sections 15 and 16 by flexible couplings 17. The sections 15 and 16 extend into the tender 6 and through the water tank 18 thereof. The pipes 10. and 11 and the sections 14 and 15 are. inclined downwardly and rearwardly from the bend 12 as shown in Fig. 1 of the drawings. The pipes 9, 10 and 11 may be formed either of a continuous length of tubing or in a plurality of sections suitably connected as desired. The sections 15 and 16 have connected thereto upwardly extending vertical pipes 19 and 20 which have their upper ends connected to forwardly and upwardly inclined pipes 21 and 22 which extend through the water tank 18 above the water line thereof. The pipes 21 and 29 extend forwardly of the tender 6 and are connected to the downwardly extending vertical pipes 23 and 21-, which terminate below the tender and form means for conveying thecinders and smoke below the locomotive and tender and onto the railroad tracks. 7 The lower surfaces of the pipes 21 and22a1f-e provided with a plurality of relatively:smalliropenings 25 which permit of any water or condensation to drop into the water tank 18. By forming the smoke conductor pipes into a pair of sections and extending the sections to the water tank of the tender at each side thereof, the water in the tender is preheated prior to its entrance into the boiler. The heat radiating surface of the sections are also increased by extending the pipesupwardly and then forwardly throughthe tender, so

as to provide a tortuous course for the cinde'rs and smoke to the water tanln It also can be seen that the hot gases can escape through the openings 25 in the pipes 21 and 22 so that they may act directly upon the feed water. a

A fan 26 is rotatably mounted in the pipe 7 and is preferably driven by an electric motor 22 which obtains its power from a storage battery or other suitable source.

to direct the smoke and cinders into the pipe 7.

w hen the engine is first started the damper 28 is preferably opened so as to allow the smoke to pass directly through the smoke stack. v

From the foregoing description it can be seen that an improved smoke and cinder conductor is provided for locomotives whereby the cinders and smoke are guided below the train and onto the railroad tracks, the conductor being so arranged as to fori'ii a feed water heater for the locomotive. While the smoke conductor has been shown and described in use with locomotives, it is under stood that the same can be used with equal successon stationary engines. r

c In practice, I have found that the form of my, invention, illustrated in the accompanying drawings and referred to in the above description, as the preferred embodiment is the most eflicient and practical; yet realizing the conditions concurrent with the adoption of any device will. necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required without sacrificing any of the advantages of my invention as set forth. 1 Y

messes hat I claim as new is a V 1. In a device ofthe class described, the combination was ai locomotive including a boiler and smoke stack, of a conductor secured to and extending rearwardly from the smoke stack, a pair of rearwardly diverging pipes secured to the conductor,said pipes being inclined downwardly and rearwardly and extendidng on each side of the boiler, and a fanrotata bly mounted-in the conductor pipe. 1 1
